In this paper, a novel solution based on weighted Laguerre polynomials finite-difference timedomain (WLP-FDTD) method is proposed for time domain analysis of interconnect modeled as a transmission line. Compared with finite-difference time-domain (FDTD) method, which is an explicit scheme and limited by Courant condition, the WLP-FDTD method is unconditionally stable since the solution is implicit...
This paper describes a new algorithm based on equivalent circuit models for simulation of dispersive transmission lines in the presence of electromagnetic interference. The finite-difference time-domain method is employed to solve the differential equations derived from the equivalent circuit models. No convolution computation is needed in this algorithm. The generalized two-port equation model of...
This paper introduces an accurate FDTD-based method for analysis of time domain response of frequency-dependent lossy transmission lines driven by CMOS gates. MOS transistors are modeled as the nonlinear alpha-power law model that includes the carriers' velocity saturation effect of short-channel devices. The dynamic behavior of CMOS gates during switching is defined in seven operation regions. Skin...
This paper introduces a numerical method for time domain analysis of the inverter driving interconnect in CMOS digital integrated circuits. To include the carriers' velocity saturation effect of short-channel devices, the alpha-power law model is used for MOS transistor modeling. Moreover, interconnect is modeled as transmission line, which is required in deep submicron technologies. Based on detailed...
